Not that I want to get involved, but springs do soften when they run in. so if they were 280 new, they will soften to that.
May be important to know the 'over the nose' pressure, should be around 700+
if the pushrods were wrong length were they hitting the arms ? ( the sides of the pushrods)
The shorter installed height is not so important as long as the srings are not bottoming out.
Moly retainers ? or titanium ?
I would think a titanium retainer should be a good fit.more importantly than a moly ( harder) retainer.

I am an honest business man and when problems like this arise, I try to stay as neutral as possible. We must all remember that we are human and not perfect. I have taken this job on to help the situation not inflate it. I hope all parties involved have the same attitude and what's important is getting to the root of the problem.. If this problem continues to be dealt with on the internet I will not continue to work on this problem. Thank You

Some preliminary observations are in:

A) The springs are supposed to be 280lbs on the seat and they show only 230lbs.

B)The push rods are potentially the wrong length.

C)The valves show clear indications of floating.

D)Some of the rocker arms registered over 45 ft/lbs of torque applied on the adjuster.

E)The valve retainers were loose and did not appear to be correct for the springs.

F)The installed height of the valves was listed as 2.00, but measured 1.940.

So what do you guys think? Should an engine be experiencing this number and level of problems with 1200 to 1500 miles? Whose fault would these problems be?

Your input here is appreciated.


Hum, that's what, 3000 or so 1/4mile runs? The valve train just needed to be replaced 500 runs ago. Put in something reasonable. 700 pound springs are ridiculous for a street car.

The rocker arms broke for one reason, you have valve bind. The only question is why.

Wow, where do you get your info a kracker jacks box. He tells you 1200 miles and you turn that in to 3000 miles and 1/4 mile runs. That motor should run for atleast 5000 mile before any adjustment to lash or distributor gear checking. And to asume that he's getting coil bind with out knowing is just a bad guess. Maybe get more info before you voice your lame guess.
